Western Bulldogs utility Liam Picken will remain out of the line up for an indefinite period of time as he continues to recover from the effects of concussion. 

Picken copped a knock to the head in the club's JLT win over Hawthorn over two weeks ago, with the club taking no chances with the 31-year-old's recovery. 

Closing in on his 200th AFL appearance, Picken remains an important part of the Bulldogs line up, kicking 24 goals from 18.6 disposals per game in 2017.
